At present, there are two methods to treat alopecia: drug therapy and hair transplant therapy. Hair loss can be treated with drugs in the early and middle stages. If drug treatment is ineffective, hair transplantation can be used after hair loss is stable. In the late stage of hair loss, because the hair follicle has been necrotic and the drug treatment doesn't work, it can only be solved by hair transplantation. The choice of hospital depends on its qualification, reputation, service and price.
